Firebase Cloud messaging doesn't work for Build variant on Android

Question

I have 2 projects in Firebase: nl.companyname and nl.companyname.acc:

This is my build.gradle:

flavorDimensions "type"
productFlavors {
    acceptance {
        dimension="type"
        applicationIdSuffix ".acc"
        versionNameSuffix "-acc"
    }
    production {
        dimension="type"
        applicationIdSuffix ""
        versionNameSuffix ""
    }
}

The download google-services.json is in directory: app/google-services.json

Android Studio is logged in to the Google account and synchronized:

The message shows up as successfully sent:

Problem description:

• When sending a message on nl.companyname, it works.

• When sending a message and targeting the device's Token ID, it works.

• But the nl.companyname.acc doesn't work.

Steps tried:

• I've deleted the .acc App in Firebase and re-added it (and downloaded the new json file).

Any help is greatly appreciated.

In the Firebase Document, it supports multiple flavor based project.

You can have multiple google-services.json files for different build variants) by placing google-services.json files in dedicated directories named for each variant under the app module root. For example, if you have "development" and "release" build flavors, your configuration could be organized like this:

app/
    google-services.json
    src/development/google-services.json
    src/release/google-services.json
    ...
